One record per week?  per day?

If it's daily, something like this would work (I'm assuming your fiscal period occurs three months before calendar period):

declare @i int = 1
declare @currentDate date = '1/1/2014'

declare @time_dim table (calendarYear int, fiscalPeriod int, calendarPeriod int, calendarQuarter varchar(10), calendarMonth varchar(10), weekno int, calendarDate datetime)

while @i <= 365
begin

	insert into @time_dim (calendarYear, fiscalPeriod, calendarPeriod, calendarQuarter, calendarMonth, weekno, calendarDate)
	
	values (
			YEAR(@currentDate)
		,	Month(DATEADD(m, -3, @currentDate))
		,	MONTH(@currentDate)
		,	cast(year(@currentDate) as char(4)) + '/Q' + cast(DATEPART(quarter, @currentDate) as CHAR(1))
		,	cast(year(@currentDate) as char(4)) + '/' + cast(DATEPART(month, @currentDate) as CHAR(2))
		,	DATEPART(week, @currentDate), @currentDate)

	set @i = @i + 1
	
	set @currentDate = dateadd(day, 1, @currentDate)

end

select * from @time_dim

Looks like you're getting an answer above, but just to throw it out here's an article on Build your own calendar table to perform complex date expressions with source code that pulls this off by day.  Scroll down to 'Now we're done modifying the table, which will look like this ' and you'll see how it looks similar to what you're asking.

I added a dateadd(m, -3, @currentDate) in the part of the code that calculates the quarter field

declare @i int = 1
declare @currentDate date = '1/1/2014'

declare @time_dim table (calendarYear int, fiscalPeriod int, calendarPeriod int, calendarQuarter varchar(10), calendarMonth varchar(10), weekno int, calendarDate datetime)

while @i <= 365
begin

	insert into @time_dim (calendarYear, fiscalPeriod, calendarPeriod, calendarQuarter, calendarMonth, weekno, calendarDate)
	
	values (
			YEAR(@currentDate) --calendar year 
		,	Month(DATEADD(m, -3, @currentDate)) -- fiscal period
		,	MONTH(@currentDate) -- calendar period
		,	cast(year(DATEADD(m, -3, @currentDate)) as char(4)) + '/Q' + cast(DATEPART(quarter, DATEADD(m, -3, @currentDate)) as CHAR(1)) -- 
		,	cast(year(@currentDate) as char(4)) + '/' + cast(DATEPART(month, @currentDate) as CHAR(2))
		,	DATEPART(week, @currentDate), @currentDate)

	set @i = @i + 1
	
	set @currentDate = dateadd(day, 1, @currentDate)

end


select * from @time_dim
